| Abstract | ||
| A study was conducted for applying three levels of potassium fertilizer in the growth characteristics, yield components, and quality properties for the following six genotypes of cotton (Gossypium hirsutum L.) ( Coker 310, Stonovill, Dun 1047 -1, Kafko-1, Montana, and Lashata).This experiment was conducted in two locations. First was field, College of Agriculture, University of Tikrit, and second was in Hawija district, Kirkuk province during the season 2010. A split plot design was used according to the Randomized Complete Block Design in factorial experiment with three replication. The potassium fertilizer was added in three doses (K0, K60 and K120 Kg / Hectare).The study included ten growth traits of yield components . The results showed that varieties differs significantly for all studied traits except vegetative branches for both locations.Adding of potassium fertilizer showed significant differences among them for all studied traits except vegetable branches and in number of opening bolls in the plants in both locations .The interaction between potassium fertilizer levels and varieties was significant in all studied traits in both locations except flowering traits in the height of first fruit branch and the number of vegetative branches , also in the number of seeds in the bolls and seed cotton yield in both locations and the range of the boll weight in university location . | ||
